Human impact on the environment in the investigated area is already evident at 4000 years BP. Temporary expansion of heathland as a consequence of agricultural land use and woodland pasture has been demonstrated to occur during latest Neolithic period, at the beginning of the Bronze Age and in mediaeval times. Late mediaeval land reclamation is reflected by increases in the pollen curves of cultivated plants and other taxa, including grasses, indicative of human activity.

Reafforestation with conifers and the establishment of crop rotation farming of the 19th century are well represented in the pollen diagram of Hardauquelle (source of river Hardau).
